Richardt Strauss is a surprise selection on the bench for Leinster’s Heineken Cup clash against the Ospreys at the RDS on Friday (8pm).

Coach Matt O'Connor has made a number of changes, although the back division sees no change from the 15 that started in the hard-fought away win in Castres last Sunday, but up front there are four changes in personnel.

However, the most surprising addition comes in the form of the fit-again Strauss selected as reserve hooker. 

The four-times capped Irish international was diagnosed with a heart condition last October and while it was initially thought that a return to action this season was unlikely, Strauss has progressed to such an extent that the medical team has cleared him to play this weekend.

Sean Cronin is once again selected at hooker for his 63rd Leinster cap, while fit-again Cian Healy scrums down beside him having impressed off the bench against Castres.

On the other side of Cronin, having been named in the extended Irish squad earlier in the week, Martin Moore gets the nod at tighthead.

Last weekend's starting props Jack McGrath and Mike Ross are held in reserve.

Devin Toner and Mike McCarthy are retained in the second row but there are two changes in the back row with Kevin McLaughlin and try scorer Jordi Murphy making way for the fit again Rhys Ruddock and Shane Jennings.

Jamie Heaslip captains the side from 8.
